Definitions

  • the present invention relates to modular conveyor belts and chains, and more particularly to a low backline pressure conveyor module and a modular conveying assembly including at least one of the conveyor modules.
  • Modular belting and chains are formed from interconnected modules that are supported by a frame and driven to transport a product.
  • Each module has a support surface which supports the product as the belting or chain is being driven along the frame.
  • Adjacent modules are connected to each other by hinge pins inserted through hinge members extending from adjacent modules in the direction of the belt travel.
  • Modular belts can transport products in the direction of conveyor travel, but have difficulty accumulating a product to reduce backline pressure. In addition, high friction products can easily damage the belt if the product is accumulated.
  • One known solution to this problem is to rotatably mount rollers directly on the hinge pin connecting modules together, such that the hinge pin supports the rollers between hinge members. The roller rotates about an axis of rotation that is substantially coaxial with the hinge pin axis. Because it is necessary to have a portion of the roller extend above the module to engage the object being conveyed to reduce backline pressure, the required roller diameter is determined by the hinge pin location and the height of the module. Unfortunately, this often results in requiring a large diameter roller that extends both above and below the module when that configuration is not always desired. Moreover, supporting the roller on the pin alone can result in undesirable pin wear.
  • the present invention provides a modular conveying assembly for reducing backline pressure when accumulating products according to claim 1.
  • the conveying assembly includes a first roller belt module having a top surface and at least one first roller axle support extending above the top surface.
  • the first axle support includes an opening.
  • a second roller belt module adjacent to the first roller belt module has a top surface and at least one second roller axle support extending above the top surface.
  • the second axle support includes an opening coaxial with the opening formed in the first roller axle support.
  • a roller axle extends through the openings of the first and second axle supports. At least one roller is rotatably supported by the roller axle to reduce friction between the roller belt modules and an object carried along the conveyer belt assembly.
  • a general objective of the present invention is to provide a belt module and a modular conveying assembly formed therefrom that can accumulate objects without severely damaging the objects or the assembly. This objective is accomplished by providing a conveyor belt module having a roller rotatably supported above the conveyor module body top surface.
  • Another objective of the present invention to provide a conveying assembly having rollers supported by the top surface of at least some of the modules, wherein the rollers are easily replaced. This objective is accomplished by providing a roller axle that extends across the modules to allow removal of the axle without disassembling modules from the assembly.
  • Fig. 1 is a perspective view of a modular conveyor belt incorporating the present invention.
  • a modular conveying assembly, or belt 10, shown in Fig. 1, includes a plurality of belt modules 12a, 12b assembled in an edge to edge relation to form the continuous belt 10.
  • Hinge pins 40 join adjacent modules 12a, 12b, and pivotally connect the adjacent modules 12a, 12b in the direction of belt travel.
  • Roller axle supports 26, 28 extending upwardly from each belt module 12a, 12b support a roller axle 42 that rotatably supports a plurality of rollers 44.
  • the rollers 44 rotatably engage an object being conveyed by the belt 10 to reduce friction between the belt 10 and the object.
  • the module 12a, 12b, or roller 44 is damaged, only the damaged component need be replaced.
  • the terms “leading" and “trailing" are used to identify features of the module 12a, 12b, the module 12a, 12b described herein can be used in any direction, or orientation without departing from the scope of the invention.
  • the modules 12a, 12b are preferably formed using methods known in the art, such as injection molding, from materials known in the art, such as acetal, polyethylene, polypropylene, nylon, and the like.
  • Each module 12a, 12b includes a body 14 having a top surface 24 surrounded by a leading edge 16 and trailing edge 18 joined by a first side edge 20 and a second side edge 22.
  • the top surface 24 can prevent products from falling through the belt 10.
  • the top surface 24 can also have perforations to allow air or fluid flow for cooling, drafting, and/or draining.
  • the module body 14 has a width which is defined by the distance between the side edges 20, 22, and a length which is defined by the distance between the leading and trailing edges 16, 18.
  • Each leading edge hinge member 30 extends forwardly from the leading edge 16 of the module body 14, and includes a coaxial opening 38 for receiving the hinge pin 40.
  • Each leading edge hinge member opening 38 receives the hinge pin 40 pivotally connecting the leading edge hinge members 30 of one module 12a, 12b to trailing edge hinge members 32 of an upstream module 12a, 12b.
  • the leading edge hinge members 30 intermesh with trailing edge hinge members 32 extending rearwardly from the trailing edge 18 also include coaxial openings 52.

  • Each axle support 26, 28 includes a coaxial opening 46 for receiving the roller axle 42.
  • the axle supports 26, 28 do not allow the roller axle 42 to pop upwardly away from the modules 12a, 12b if the roller 44 or roller axle 42 catches an object.
  • modules 12a, 12b are configured in a belt arrangement, i.e. two or more modules 12a, 12b define the belt width and are arranged in a side edge to side edge and leading edge to trailing edge configuration, such as shown in Fig. 1 or a bricklaying configuration
  • the modules 12a, 12b defining the belt width edges have the end axle supports 26 proximal the belt width edges.
  • module 12a has a first module width that is different than module 12b having a second module width to form a belt 10 having a desired width equal to the sum of the first and second module widths.
